'UIdBRELLA-STRAP RING.

Application filed. September To all whom it may concern:

Be it known that I, EMIL GRIMALDI, a citizen of the United States, residing at New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Umbrella-Strap Rings, of which the following is a specification.

This invention relates to umbrella straps and has particular reference to umbrella rings of such straps designed for buttoning or otherwise engaging over a button at the other end of the strap in a well known manner.

Among the objects of the invention is to provide a ring having peculiar construction as to the covering or wearing surface thereof so as to produce the most pleasing appearance as well as to protect the metal part of the ring from exposure.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a plan view of an umbrella strap with one of my improved rings attached thereto.

Fig. 2 is an enlarged detail view showing the manner of wrapping the stock from which the rings are made.

Fig. 3 is a plan view of a ring before the strap is applied.

Referring now more specifically to the drawings I illustrate a ring 10 and flexible strap 11 which broadly are for their usual purposes in binding or embracing a folded umbrella.

The manner of formation of the rings is shown in Figs. 2 and 3. Each ring comprises a core 12 of metal wire or its equivalent having sufficient rigidity and body for its purpose. This wire is first wound as indicated at 13 with a suitable fibrous material such as cotton, silk, or the like. Then again, a winding at 14 is made upon the e, 1923. Serial No. 660,765.

inner winding 13. The winding 14; is of a different character as to right and left hand from the inner winding, and is preferably made from a composite strand of wire 14 covered by a fibrous covering 14" of any suitable texture such as cotton, silk, or any combination of diflerent materials. Prefer ably, however, the outermost coating is of silk for the sake of best appearance and wearing qualities. The wire core 14 of the outermost winding is sufficiently stiff to hold said outer winding in place even though the ends are clipped. The function of the inner winding 13, is to act as a cushion to prevent the cutting of the outer fiber 1 1 when the winding 14 is wrapped snugly about the core 12, while at the same time allowing of a more or less resilient and consequently more even pressure as between the core 12 and the winding 14. This function is of particular value in aiding toward the proper formation of the ring, since it is essential that the resulting grinding action, caused when the helical wire 14 slips upon the core 12, does not impair the structure of the silk fabric.

After'the stock is made as indicated the rings, as shown in Fig. 3, are made by ,clipping off suitable lengths of the stock and bending them so as to form a portion 10 of arc shape and with straight ends 10 abutting against or close to each other at the joint 10 so as to make a bearing at 15 for the strap which is looped therearound and stitched or otherwise secured as at 16. The loop of the strap covers the joint of the ring and of course prevents any possible fraying or raveling of the ends of the wrappings. The character of the covering, of the wire core 12 is such that the ring in use is of the best possible appearance and durability and of course the coverings may be made of any suitable colors as well as materials.

I claim:

1. The herein described ring comprising a core ofrelatively stiff material and having straight abutting end portions, a winding of fibrous material surrounding the core, and a second winding surrounding the first mentioned winding and constituting a finished ornamental coating.

2. The herein described ring comprising a core having abutting straight end portions, a Winding of fibrous material surrounding the core, and a second winding surrounding the first mentioned Winding and constituting a finished ornament] coating, said second Winding including a Wire core and an outer relatively expensive fibrous winding, the cutting of Which, While the ring is being formed, is prevented by the resilient action of the first mentioned Winding.

In testimony whereof I affix my signature.

EMIL GRIMALDI.
